| Abstract: | The implementation of the most recent collisional Aarseth N-body integrator with Ahmad-Cohen scheme NBODY6++ on a general purpose massively parallel computer (CRAY T3D) is described. The performance is compared to standard computers and the results are compared to previous performance analyses of direct N-body integrators. A critical revisit of the optimal neighbour number in Ahmad-Cohen schemes shows, that for some special purpose and parallel computers it is much smaller than expected. |
